The Leica clearly merits a higher score for Magic & Sparkle, but in ‘sharpness’ terms, it’s too close to call here: both the Elmarit and the Canon zoom are wiry. We’ll not see the best of the Olympus for another stop yet.

Focus on the grass and the Canon looks more attractive; look at the horizontal ridges in the plasterwork and the Leica shines. It really is a horses for courses thing.

By f5.6 the Leica 19mm is well on the way to turning in a useable corne. The Canon 16-35mm needs at least another stops to arrive here and the Olympus won’t hit its stride until f11 . . .
